Spectroscope
  •      Scientists use tools to help them understand the universe, galaxies, stars, and planets.  A major tool used to gather information about these objects is called a spectroscope.  The scientific technique that utilizes the spectroscope is called spectroscopy
  • HOW DO WE KNOW SO MUCH ABOUT STARS?
  • Being that humans have never actually visited another galaxy, a star, or a planet, how do we know so much about them? 
  •      Scientists learn a lot about these objects from the light that they send us.  The light received can tell us about the objects.

Find the density of the object below.

The object was placed on a triple beam balance.

20

0

An object was dropped into a graduated cylinder that contained 40 mL. Determine the volume of that object.

5.4

Image from http://www.edinformatics.com/math_science/mass.htm

slide11

The solution …

Volume = Volume of water & object – volume of water

V = 65 mL – 40 mL

V = 25 mL

M = 25.4 g

Density = Mass ÷ Volume

D = 25.4 g ÷ 25 mL

D = 1.01 g/mL

** The object will sink!

Find the density of the object below.

An object was dropped into a graduated cylinder that contained 20 mL. Determine the volume of that object.

The object was placed on a triple beam balance.

The mass

slide13

The solution …

Volume = Volume of water & object – volume of water

Volume = 43 mL – 20 mL

V = 23 mL

M = 373.3 g

Density = Mass ÷ Volume

D = 373.3 g ÷ 23 mL

D = 16.23 g/mL

Use a periodic table and your knowledge of the element families to identify each element by name.

1. I am a Noble Gas that is found in the 6th period.

2. I am a member of the Alkaline Earth family and have 88 electrons.

3. I am a transition metal that is a liquid at room temperature.

4. I am a member of the Carbon family that is found in the 5th period.

5. I am a Halide (group 7) that is a gas at room temperature and have 3 energy levels.

slide15

The answers are …

1. I am a Noble Gas that is found in the 6th period.

2. I am a member of the Alkaline Earth family and have 88 electrons.

3. I am a transition metal that is a liquid at room temperature.

4. I am a member of the Carbon family that is found in the 5th period.
